Loch Turret reservoir is situated near the head of Glen Turret near Crieff.
It lies to the South East of Ben Chonzie which is sometimes referred to as Scotland's most boring Munro. I haven't climbed it yet so can neither confirm or deny if it is boring - but anyway, all hills have their attractions.
Loch Turret is quite a large loch at 378 acres.
If you are interest in fishing Loch Turret, the fishing is controlled by Crieff Angling Club - more information here: http://www.crieffanglingclub.org.uk/prices.htm
